To all whom it may concern:

Be it known that I, Gnoiion MoLYNEU PARK, acitizen of Great Britain,"residing at Roden, Gorse Road, Blackburn, in the county of Lancaster,England, have invented an Improvement in Apparatus for Cooling Clinkerin the Manufacture of Cement and for like Cooling Purposes, of which thefollowing is a specification.

My invention relates to improvements upon the existing-method of coolingand treating clinker, in which hot clinker from the kiln is deposited bymeans of a chute, in a circular rotating tank, and sprayedwith watertherein, thereby hydrating the free lime in the clinker and on itssurface, and greatly improving its quality.

The clinker is subsequently removed from this tank by lifter plates, anddeposited, by means of a second chute, into, and carried through, arotating tubular body, into a series of superimposed circular revolvingtrays, having communicating holes from one to another, commencing at theinner one,by which the clinker, considerably cooled by its subjection tothe action of the water and by its passage through the tubular body, ismade to travel the entire circumference of each tray in succession,finally being discharged from the outermost tray on to a conveyer orother handling apparatus.

The objects of my invention are, firstly, to pass a large surplus ofwater through the circular rotating tank; secondly, to produce andcollect a continuous quantity of heated water by direct Contact with thehot clinker; which water being at, or near boiling point, can, afterfiltration, be used for boiler feed or other purposes; thirdly, theclinker is greatly improved by reason of the free lime before referredto; fourthly, according to another arrangement, I apply my rotary tankto the ordinary tubular cooler com monly in use, to effect the objectsalready described.

I attain these objects by the apparatus illustrated in the accompanyingdrawings, in which- Figure 1 is a longitudinal vertical section.

Fig. 2 is a transverse vertical section of one-half the rotating tank,and its casing.

Fig. 3, is a vertical longitudinal section, on an enlarged scale, of theupper portion of the rotating tank and its casing.

The first rotating tank A, is shown as formed of two circular steelplates D and tion, steel bar; or this may be formed of a,

perforated steel plate.

The bars shown are held in position by a number of suitably shapedcastings or. G, G, etc. and the whole is fixed by a lcng bolt H, passedthrough each casting G, and securely tightened up outside'of thecircular back and front plates D and E.

To'each back and front plate D and E, is secured a channel, or dripflange, J, J, and the whole rotatin tank is encircled by a steel platehood lljsitting on a receiving trough or tank L. This hood is furtherprovided with drip flanges 1L rep n v I The -ob ect of this hood and itsdrip flanges is to catch any escaping steam and collect the resultantmoisture and lead it down into the receiving trough L.

Inside the first circular rotating tank A are lifting plates N, N, Netc. which are perforated; while those similar plates shown at O, O, 0etc. are plain. The feed chute from kiln into tank is shown at P, andfrom thence to body of machine at R.

I claim:

1. Apparatus for cooling clinker comprising a rotary chamber adapted toreceive cold water, an inner ring or circumferential screen positionedwithin said chamber adapted to receive, retain and lift hot clinker onits surface while permitting passage of water therethrough, drip flangesat the exterior circumference of the chamber adapted to facilitate thecollection of the heated water produced by the contact of the cold waterwith the hot clinker and a means for receiving the heated water fromsaid chamber and drip flanges.

2. Apparatus for cooling clinker comprising a rotary chamber of circularcross section adapted to receive cold water, an inner perforated ring orcircumferential screen positioned within said chamber, means for feedinghot clinker to the surface of said screen, means on said screen forretaining and lifting the hot clinker while in contact with the water,drip flanges at the exterior circumference of the chamber adapted tofacilitate the collection of heated water produced by said contact ofhot clinker and cold water and a receptacle below the chamber forreceiving the heated waterfrom said chamber and drip flanges.

3. Apparatus for cooling clinker comprising a rotary chamber adapted toreceive cold water, an inner ring or circumferential screen positionedwithin said chamber and adapted to receive, retain and lift hot clinkeron its surface while permitting passage of water therethrough, dripflanges at the exterior circumference of the chamber adapted tofacilitate the collection of heated. water produced by the contact ofcold water with the hot clinker, a casing inclosing the chamber leavingan annular space around same, drip flanges on said casing within saidannular space to collect and direct condensed steam or vapor and meansfor receiving heated water and products of condensation from saidchamber and drip flanges.

5!. Apparatus for cooling clinker comprising a rotary chamber ofcircular cross section adapted to receive cold water, a perforated ringor circumferential screen positic-ned within said chamber means forfeeding hot clinker to the surface of said screen means on the latterfor retaining and lifting the hot clinker while in contact with thewater, drip flanges at the exterior circumferonce of the chamber tofacilitate the collection of the resultant heated water, a hood or covercircumferentially inclosing the chamber leaving an annular space aroundsame, drip flanges on said casing within said annular space to collectand direct condensed steam or vapor, and a receptacle below the chamberfor receiving heated water and products of condensation from saidchamber and drip flanges.

5. Apparatus for cooling clinker comprising in combination a rotarychamber, adapted to receive cold water, an inner ring or circumferentialscreen, positioned within said chamber and adapted to receive, retainand lift hot clinker on its surface, while permitting passage of watertherethrough, drip flanges at the exterior circumference of the chamberadapted to, facilitate the collection of heated-water produced by thecontact of the cold water Withthe heated clinker, means for receivingthe heated water from said chamber and drip flanges, rotary coolingdevice djac nt Said rotary chamber and means for transferring theclinker from the screen within same to said cooling device.
